Kapton is used extensively on spacecraft primarily as flexible substrates for lightweight, high - power solar arrays because of its inherent strength, temperature stability, excellent insulation properties, ultraviolet ( uv ) stability and infrared ( ir ) transparency. however, polymeric material undergoes severe degration after being exposured on atomic oxygen ( ao ) in low earth oribit ( leo )
聚合物kapton由於具有較高的比強度，優越的熱穩定性、絕緣性、紫外線輻射穩定性及紅外線穿透功能，是航天飛行器常用的材料，但由於空間環境中的原子氧對這種材料造成極大的損害，大大限制了這種材料在空間環境下服役時間。Radioactive matter is incorporated into plants, which are then eaten by animals with the result that most foodstuffs have a measurable amount of radioactivity. additional radioactivity in food comes from the naturally occurring isotope carbon 14. some cosmic radiation also reaches sea level
植物亦混有輻射物質，而動物吃掉植物，以致絕大部份食物也含有一定輻射食物輻射也來自天然的同位素碳十四，此外，宇宙輻射亦可穿越大氣層照射到海面。
